Guidelines for Safe and Efficient Use

In summary, we do not have enough information at this point to assure the

public that there are, or are not, any low incident health problems associated

with use of mobile phones. FDA continues to work with all parties, including

other federal agencies and industry, to assure that research is undertaken to

provide the necessary answers to the outstanding questions about the safety of

mobile phones.

What is known about cases of human cancer that have been

reported in users of hand-held mobile phones?

Some people who have used mobile phones have been diagnosed with brain

cancer. But it is important to understand that this type of cancer also occurs

among people who have not used mobile phones. In fact, brain cancer occurs

in the U.S. population at a rate of about 6 new cases per 100,000 people each

year. At that rate, assuming 80 million users of mobile phones (a number

increasing at a rate of about 1 million per month), about 4800 cases of brain

cancer would be expected each year among those 80 million people, whether

or not they used their phones. Thus it is not possible to tell whether any

individual’s cancer arose because of the phone, or whether it would have

happened anyway. A key question is whether the risk of getting a particular

form of cancer is greater among people who use mobile phones than among

the rest of the population. One way to answer that question is to compare the

usage of mobile phones among people with brain cancer with the use of

mobile phones among appropriately matched people without brain cancer.

This is called a case-control study.

The current case-control study of brain cancers by the National Cancer

Institute, as well as the follow-up research to be sponsored by industry, will

begin to generate this type of information.

What is FDA’s role concerning the safety of mobile phones?

Under the law, FDA does not review the safety of radiation-emitting

consumer products such as mobile phones before marketing, as it does with

new drugs or medical devices. However, the agency has authority to take

action if mobile phones are shown to emit radiation at a level that is hazardous

to the user. In such a case, FDA could require the manufacturers of mobile

phones to notify users of the health hazard and to repair, replace or recall the

phones so that the hazard no longer exists.

Although the existing scientific data do not justify FDA regulatory actions at

this time, FDA has urged the mobile phone industry to take a number of steps

to assure public safety. The agency has recommended that the industry:
